` Specification of Letters Patent.

Patented Nov. 19, 1907.

. @unmanned-March19.1907. saairaaazav To all whom it may concern:

Beit known that I, HENRYAUCHU, citizen of the United States, residing at Emporium,

' in the county of Cameron, State of Pennsylvania, have invented certain new and useful Improvements 1n Gas-Condensers, of which the following .is a specification, reference being had therein to the accompanying draw lng.

This invention relates to a gas condenser,

. and particularly to an apparatus by which the obnoxious gases from V.industrial entern p'rises which tend to contaminate the atmospheremay be condensed and controlled.

The invention has for an object to provide means for conveying the gases and fumes from acid liquid treating apparatus, and smp'ke, orl other deleterlous gases arising from exhaust flues or clumneysto a conduct- .,ing pipe through' which a stream of water passes and by the deflection of the course of the liquid to thoroughly absorb the gases ntherein and to discharge them at a proper ppint to prevent their emerging into the at- Inosphere which is detrimental to7 animal ,life and vegetation and thereby relieving the lsurrounding air of all objectionable gases in fthe vicinity of industrial enterprises.

RA further object of the invention is to pro- Ivide an improved construction of a heating Y panin connection with which the conducting stack'is disposed.

Other and further objects 'and advantages i of the invention will be hereinafter set forth of the and the novel features thereof defined by the ap ended claims.

the drawing :'-Figure 1 is an elevation apparatus with parts of the conducting pipe in section; Fig. 2 .is a detail section through the acid' heating pan, and Fig. 3 is a lan of thek pan ywith cover plates in dotted ines.

Like numerals refer to like partsinj the several views of the drawing.

In the apparatus illustrated in Fig. 1 two .forms of acid heating pan are shown, the one Y on the right comprising thefurnace 1, of any with'a seat 6 in Which'the lower end of n "desirable character, having disposed at its upper portion the pan 2 which is formed of heavy cast metal provided with the central support 3. At the edges of this pan the su porting flange 4 is provided upon which t e outer edges of the tilecovers 5 rest, the meetingledgesof these covers .being supported by 'thep'o'rtion 3. One of these covers is prof the stack 7 is disposed. T his stack is formed of any desired material, preferably Qf heavy cast iron pipe sections tightly connected together, and the weight thereof maybe sup? orted vby hangers 8 extending downwardly from the roof structure 9 of the building and ,pipe being disposed with the chferent por-' tions thereof atan angle to each other7` for ,instance, the section V13 connected by an elbow 14 with the section 12 and disposed at a right an le thereto, while the section 15 is connectedylan elbow 16 with the lower end ofthe section '13. and also by an elbow 17 .with the discharge section 18 -partiall'yor completely submerged as may be desirable. This conducting 'pipe is supplied with. a stream of water from any deslred source, for

instance the nozzle 19 at the'upper ortion, which owing to the deflections of t e pipe bring the water and gases into intimate contact thus absorbing theA acidI fumes in the body of liquid. Under some conditions it is desirable to produce a' draft from the pan to assist in withdrawing the fumes through the stack, and this may be accom lished by means of the air or steam pipe 20 avinfr the connection 21 at the upperl portion of? lthe stack 7 i In the form of the invention shown at the left o f Fig. 1, the furnace 22 is .provided with the pan 23 similar in constructlon' to the p'an- 2 from which the conducting pipe 24 extends to the condenser 25 and from thence to the l usual coke filled tower 26 which at its upper end is provided with the fume stack 27 communicating with the conducting pipe 12 and l also with the draft pipe 20 by means ofthe connection 28, f

This invention cffectually frees the atmos? phere from the slightest trace of esca ling gases from an acid treating plant whic in y the case of such acids as nitric and sulfuric are-'absolutely destructive to both animal life and vegetation and very offensive when emerging into the atmosphere gotha@ much expense and difficulty has beeirexperenced in conducting such works in any populated `H0 locality. L The condenser provides means to prevent the escape of h'ot acid fumes into the S into the atmosphere after" all of the easily open :iii` and conducts these fumes to a pipe where they are brought into contact with a sii-cani oli water which rapidly absorbs the hot acid gases and discharges them into an.

adjacent creek, tank or at any other vpoint at which the lower end of the pipe is submerged- The dellection of the conducting pipe forces the water passing therethrough to shoot across the internal diameter of the vertical' sections thus exposing a greater surface area' to Athe action of the fumes so that when discharged they are thoroughly absorbed bvthe water. j

Tlie apparatus is designed to condense and absorb those fumes which naturally escape condensed gases are condensed and converted into their respective liquids',`an'd is particularly adapted for use in boiling acid to remove thel water therefrom'. sonic conditions it is desirable to produce a draft or suction from the heating 'pans and to assist in forcing the fumes through the conducting pipe, and for this `purpose a I)et of vao steani or air is forced into either the stack or conducting pipe at any desired point.

It will be obvious that the invention is applicable to any forni of acid treating ap a ratus and is particularly adapted for that herein illustrated and described.

Having described n'iy invention and set lorth its nicritsg what 1 claim and desire to lsecure-by Letters Patent is 1. The combination with agas dischargiiig stack, ot a conducting and absorbing pipe located lat and connected with the top of said stack and extended .in straight lines laterally andvertically downward, the sections of. said extension being united by curved connections, and a Water supply connected to the upper portion of said absorbing pipe and having a capacity less than that of said pipe.

2. T e combinationwith a gas discharg- 4ingstack, of a conducting pipe located at and connected with the top of said stack and comprising straight sections' connected at their intersections and extending laterally and vertically downward from said stack,-

the downward section of said pipe being of greater length than the lateral section thereper portion of `saidipi e and having a capacity less than that o the pipe. Under 3.
